10 Gb/s framer/demultiplexer IC for SONET STS-192 applications

摘要

This paper presents the first ever reported 10 Gb/s SONETframer/demultiplexer IC which integrates the functions of serial toparallel conversion, byte alignment and frame detection on a singlechip. This IC identifies the SONET framing pattern from the inputSTS-192 data stream, and converts the serial input bit stream into abyte-parallel, frame-synchronized output data stream. It is implementedusing a high-current gain baseline AlGaAs/GaAs heterojunction bipolartransistor (HBT) technology, consumes approximately 3 W of power using a-5.2 V supply, has a phase margin of 270° and differential inputsensitivity of 100 mV_p-p at 10 Gb/s
